[PRIMARY SQUAMOUS CELL CARCINOMA OF THE PROSTATE: A CASE REPORT].

SQUAMOUS CELL CARCINOMA, prostate carcinoma, The patient was a 67-year-old man who visited our hospital with urge incontinence. His serum prostatic specific antigen level was normal (1.191 ng/mL).

[Unclassified renal cell carcinoma accompanying pyonephrosis: a case report].

A 73-year-old male, admitted to a local hospital because of fever and consciousness disturbance, was referred to our institute. He had a history of long-term steroid administration and diabetes mellitus. Under diagnosis of severe right pyonephrosis associated with severe inflammatory response syndrome as well as disseminated intravascular coagulopathy, he was transferred to our hospital.

A single-dose regimen for antimicrobial prophylaxis to prevent perioperative infection in urological clean and clean-contaminated surgery.

A single dose of antimicrobial prophylaxis (AMP) was administered parenterally for the prevention of perioperative infection in a total of 788 patients undergoing urological surgery, including 380 endoscopic-instrumental, 328 clean, and 80 clean-contaminated operations performed at our institute between January 2007 and December 2009. Surgical site infections (SSIs), urinary tract infections (UTIs), and remote infections (RIs) were prospectively surveyed. The definition for a single dose of AMP allowed for the administration of an additional dose of an antimicrobial during surgery if the procedure was longer than 3 h, but not for the parenteral or oral administration at the end of the procedure in the recovery room, or at a later time over a period of more than 24 h.

Hydrodistension under local anesthesia for patients with suspected painful bladder syndrome/interstitial cystitis: safety, diagnostic potential and therapeutic efficacy.

Objectives: To evaluate the safety, diagnostic potential and therapeutic efficacy of cystoscopy with hydrodistension under local anesthesia in patients with suspected painful bladder syndrome/interstitial cystitis (PBS/IC).

Methods: Thirty-six patients with frequency, urgency or bladder pain for > or = 6 months and an average voided volume of <200 mL were enrolled in the study. Hydrodistension was carried out 10 min after instillation of 10 mL of 4% lidocaine.

cDNA macroarray analysis of genes in renal epithelial cells exposed to calcium oxalate crystals.

Kidney stone formation is a complex process, and numerous genes participate in this cascade. The binding and internalization of calcium oxalate monohydrate (COM) crystals, the most common crystal in renal stones by renal epithelial cells may be a critical step leading to kidney stone formation. Exposure to COM crystals alters the expression of various genes, but previous studies on gene expression have generally been limited.

Plasmacytoid urothelial carcinoma of the urinary bladder: a case report and immunohistochemical study.

We report a rare case of plasmacytoid urothelial carcinoma (PUC) of the urinary bladder. A 50-year-old man complained of pollakiuria and urinary incontinence. MRI detected a bladder tumor invading the rectum and bilateral hydroureteronephrosis.

Calcium phosphate-induced renal epithelial injury and stone formation: involvement of reactive oxygen species.

Background: Crystal formation and retention are critical events for the formation of kidney stones. Oxalate and calcium oxalate (CaOx) crystals are injurious to renal epithelium, and membranes of injured cells promote crystal adherence and retention. Calcium phosphate (CaP) is the most common crystal in both urine and stones, most likely to form in the early segments of the nephron and can nucleate CaOx in a metastable solution.
